A given supplier since 1918

Hard is soft

We see steel as something soft and malleable. Because even though steel itself is hard, it is almost as fragile as an egg during work. The softness is also expressed in our values as we have an active approach to sustainability.

Sustainability & CO2

Take responsibility for a more sustainable world and future we see as something completely natural. Sustainability covers several different areas, such as sustainable business, financial sustainability, and a healthy and good working environment for our employees. Then of course our external environment which is a cornerstone. Today we measure our CO2 footprint and can report this at article level.

Fine Blanking

Fine blanking of products with requirements for functional surface and tight tolerances.

Punching

Punching of complex or simple products in several different metals

Pressing

Pressing and punching of advanced products with precision in shape, depth and surface

Laser cutting & Milling

Figure cutting in sheet metal with the opportunity for after- treatment in a milling machine.

An easy choice to choose us, just sayin.

How many companies can show experience since 1918?

100 years of production makes us a complete and the obvious choice as a supplier from prototype to series production

Nd:YAG and disk lasers in laser cutting 

Nd:YAG: A solid-state laser where the laser-active medium is a YAG crystal doped with neodymium. It provides a wavelength of around 1064 nm, high precision, and the option of both pulsed and continuous operation. Nd:YAG is often used for finer details, thinner materials, and the combination of cutting/welding. 

Disc laser: A further developed solid-state laser where the laser-active material is a thin disc mounted against a cooling plate. This provides very stable beam quality, high efficiency, and is well suited for automated high-volume production in metal, with narrow cuts and good repeatability.

What is eccentricity? 

Eccentric pressing is a method of sheet metal pressing that uses an eccentric press to shape or cut metal using high, repeatable strokes.

Fiber laser 

A fiber laser creates light in a diode-pumped, rare-earth-doped glass fiber (often ytterbium). The same fiber both amplifies and guides the light to the cutting head. There, the beam is focused to a very small point of high energy density. The result is a narrow cutting gap (kerf), high speed and good detail reproduction-especially in thin to medium-thick sheet metal and in reflective metals such as aluminum and copper.
